RELEASE-RIGGING.

To (/U vahomizf may concern:

Be it known that I, \VALTER P. MURPHY, a ('ltlZQll of the United Eatates, residing at Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Release-Rigging, of which. the following is a specification.

The object of my invention is to provide a release riggingfor car couplers, comprising a rock shaft which is flexibly connected at its inner end with the locking pin and is provided with a lever intermediate .its ends extending upwardly and rearwardly therefrom, from which is bodily suspended an operatinghandle, whereby the .shaft may he rotated and the locking pin operated when the handle is pushed-bodily downward or is moved in an arc; and with this and other objects in View, my invention consists of the parts and combination of parts as Twill be hereinafter pointed out.

In the drawing: Figure 1 is an end elevation of a car (broken away) equipped withmy improved release rigging. Fig. 2 is a top plan view of the same. Fig. 3 is an enlarged detail vertical sectional view on the line 33 Fig. 1 looking in the direction of the arrows. Fig. 4 is an end elevation of a car (broken away) with "a release rigging.

secured thereto showing another embodiment of my invention. 5 1s a vertical sectional view on the line 5--,5 Fig. 410010,

ing in the direction of the arrow. Fig. 6 IS a detail perspective view of stlll another embodiment of my invention. Fig. 7 a detail perspective view of still another'embodiment of my invention. I

-The reference numeral 8 designates acar and 9 the coupler.v The release rigging rock shaft 10 is revolubly mounted in brackets 11 secured to the car; the inner end of the rock shaft ternnnating in a forwardly extending crank 12 which is flexibly connected with v the locking pin of the coupler. The rock shaft is provided intermediate its ends with a lever 12 which, when the shaft 1s in operative position on the car. extends rearward-1y and upwardly at an acute angle from the rock shaft toward the canand is provided with a bolt opening nearits upper end.

13 is a handle. terminating at its upper end in a yokelel, the arms of which straddle the. lever 12 to which they are pivotally secured by means of a. bolt 15, whereby the handle is bodilv suspendedi ,fron1 the lever 12 Specification of was Patent.

intermediate-the ends ofthe rock shaft.

JThehandle 13 termin-ates'at its lower end in an outwardly extending crank 16 which lies, normally, in'a plane beneath the plane. of the underface of the car or end sill of the car where-it is within easy reach of the brakeman, whether he is standing on the road bed or on the usual side ste of the Car.

Referring to Figsd and 5 t e reference numeral 17 designates the rock shaft of the release rigging suitably mounted on the car by means of the brackets 18. This lever is provided, intermediate its ends, with a lever 19, of the box type,,extending upwardly therefrom, toward the car, at an acuteangle. 19 'is an operatinghandle, the upper" end of which is rebent'to form an. eye 20 which is disposed around the upper end of,

the lever 19 as more clearlyshown in Fig. 5, whereby the handle is suspended bodily from said lever between the rock shaft and the car. The lower, end of the handle 19 terminates in an outwardly extending crank '21, which, normally,'lies in a plane below the plane of the underface of the 'car in which position it may be easily operated by the brakeman from the road bed'or from the car.

In Fig.6 I have shown' another embodishaft- 22 is brokenaway. The rock shaft 22 is provided, intermediate its ends, with a lever 23 which extends therefrom .rear-' wardly and upwardly toward the car body. This lever 23' is formed-by closed return bend of the shaft, the portions 24 abutting and constituting a fulcrum. when the operating handle is operated as alever of the first order as will he hereinafter explained. The operating handle 23 terminates at its upper end in a return bend to form an eye 26 which engages the lever 23, as shown, the lower ment of my invention in which the rock end of the handle terminating in'an out.-

wardly extending crank21 which is normally in a. plane beneath the plane of the underface of the car or end sill as heret0-' fore explained in connection with the other embodiments of my invention.

In Fig. 7 the'rock shaft 28 is shown broken away. The rock shaft 28 is provided,

intermediate its ends, with. a lever 29"which' extends therefrom rearwardly and upwardly toward the car. 30 is an operating handle which is rebent at its upper end to form an enlarge'd eyeor ring 3] which is at right angles to the crank 32 the lower end of a fulcrum for said the handle the sides of the yin" eontac tiln 7 a b with the shaft 28 when the handle is used a lever the first order, the shaft act ing as fulcrum. The handle 80, as in the other embodiments-1, is suspended hodilyfroin the lever 29 between the shaft and the car.

From the above description it Will be seen that a bi'akeinan standing on the usual side step of a car may operate. the locking pin of the coupler by pressing downward with his foot on the crank of the opera ing handle thus pushing the handle downward hodily in :t' vertical plane thus, through the lever on the rock shai't, (whieh operatesias a crank) rotate the reek sha t and operate the locking pin of the ('(lllpitl.

Then standing on the road hed beside the car, the brakeinan may pull en the. crank of the operating handle and swing said handle in an axe. whereupon the handle,

near its upper end, is brought into eontaet with the lock shaftand said shaft .stn'ee as dle becomes a lever of the first order, and rotates the shaft thereby operating the locking pm of the coupler. Thus it will be seen that the reel; shaft inav he rotated either by handle, whereby the hanl l I l l l l i i i l l l l l 1 a vertical plane nimement or an aruuate movement of the eperiiting handle.

' hat I claim is: 1. In a relea e rigging For couplers, a rock s hajl t eonneetz-d with the coupler pin at its inher end, a crank on said Sl'litfhiIltGI mediate its ends and extending upwardly and .rearuardl 'heretroni, an operating handle suspended hedily from said eranlgwhereby the shaft is rotated when the handle pushed bodily downward, and said handle engaging said" shalt intermediate its ends whereby said shaft is rotated when the handle'is moved in an arc.

li] a releaserigging 'lnr ear couplers, a hilt to ,operate the lot-king pin ml the eeuplei', and having anetl'se't. and an operating handle suspended. lmdily trmn said oil'r -ret and lltH'll'lQ a. further o nrratite point rd? connection with sa d shalt.

In testim urv whereof I allix my signature in PIGFK'UCG of two witnesses.
